• Protect against physical damage.
• Use adequate ventilation and dust collection.
• Practice good housekeeping.
• Do not allow dust to collect on walls, floors, sills, ledges, machinery, or equipment.
• Where possible dampen materials before re-working.
• If dust generation is unavoidable, local exhaust ventilation or good natural ventilation should be
employed.

8. Exposure Controls/Personal Protection
Generating dusts from this product should be avoided.
• VENTILATION: Provide local and/or general exhaust to control dust generation below exposure
limits. Local exhaust ventilation is generally preferred because it can control the emissions of the
contaminant at its source, preventing dispersion of it into the general work area.
• RESPIRATORY PROTECTION: Wear a NIOSH approved mask for control of nuisance dust.
Respirable dust levels should be monitored regularly.
• EYE PROTECTION: Wear safety glasses with side shields to protect against eye contact.
• SKIN PROTECTION: Wear general purpose work gloves to protect skin from irritation. Wash
periodically exposed skin with soap and water. Rinse wet kiln dust mixtures from clothing to prevent
skin contact.
